OP has the right analysis, I think. It's not the mass of the seat itself but
the way it interferes with the (reflexive, especially in a long-time
paddling team) balance adjustments in the upper body. Maybe a low-back or
lumbar support would be a useful compromise.

Like a k**** seat.

Why New Years Sucks

snip

And so, the perfect metaphor for that relationship -- the most perfect
metaphor for my luck in love is how we ended up celebrating New Years.
I spent it in Chicago, at my neighbor's party, jetlagged and a little
heartbroken after a short trip alone to Europe, wondering what was so
wrong with me that I was destined to be unlovable, while he spent it in
Casa-****ing-Blanca, Morocco with a couple of close friends. Oh, the
irony! Casablanca. Without me! As in, I wasn't even invited.

What's really shameful is that I stayed with him another 3 months after
that, and then I wasn't even the one to really suggest the breakup,
though it did seem the healthiest choice when we got down to it. It
took months to get over him, months to stop missing him, to feel happy
just being alone. But when I finally did move on, I had some
revelations about what it is I'm looking for, and top of the list is
not having to convince someone to be into me. Also, if you're going to
go to Casablanca, you better damn well take me with you.

I Can't Make You Love Me
Mike Reid and Allen Shamblin
performed by Bonnie Raitt

Turn down the lights
Turn down the bed
Turn down these voices
inside my head

Lay down with me
Tell me no lies
Just hold me close,
don't patronize

Don't patronize me

Cause I can't make you love me
if you don't
You can't make your heart feel
something it won't
Here in the dark
in these final hours
I will lay down my heart
And I'll feel the power
but you won't
No, you won't
Cause I can't make you love me
if you don't

I'll close my eyes
then I won't see
the love you don't feel
when you're holding me

Morning will come
and I'll do what's right
just give me till then
to give up this fight
and I will give up this fight

Cause I can't make you love me
if you don't
You can't make your heart feel
something it won't
Here in the dark
in these final hours
I will lay down my heart
And I'll feel the power
but you won't
No, you won't
Cause I can't make you love me
if you don't
